Wrong wind turbine wake

Hello,
I can't understand why the turbine wake moves upwards. The impacting air flow on the rotor always comes from the same direction (left), however, arrived at about 1 second of the simulation, the wake starts to move. I attach two images to better understand the problem. How can I solve it? Thanks so much PS: I'm new in the forum, can you attach .sim files? Because my file was rejected, even as a .zip extension. |

Hello AlphaDelta
I think you have to check the boundary conditions. https://www.youtube.com/watch?v=g1Tmz_Ut2Uw |

Thanks.
Where could the wrong boundary conditions be? On the edge of the domain? At the interface between stationary and rotating regions? |
